Just think about what market Google entered in the first place. It was a market with things like altavista.com being the dominant search engines.
Facebook was first, so now it has squatters rights? I don't think so.

Google dominated because it did search much better than it's competitors and got people the search results they were looking for.
Google+ does nothing for me that I cannot get with Facebook.
I merely make a comparison between the early days, intentions and motives of both Google+ and Facebook, how they're different and why I think that difference is important.
